Compounding means a return can earn a return of its own, when it stays invested. Imagine one thousand growing at five percent a year. It becomes one thousand and fifty, then one thousand, one hundred and two fifty. That extra two fifty is growth on the first return. This is an illustration, not a forecast. Real returns vary, and investments can lose value.

A short narrated explanation. The full guide continues below.
Growth can begin earning growth
Start with a hypothetical 100. At a steady 6% annual return, with no costs or withdrawals, it becomes 106 after one year and 112.36 after two. The second year's 6.36 includes growth on the earlier growth. That is the mechanism of compounding.
Regular contributions add another force: more of your own money enters the plan. Keep those deposits separate from the growth when reading any chart.
Read the assumptions before the big number
Our illustration starts at zero and adds 200 at each month-end for 20 years: 48,000 of contributions. A constant 6% effective annual return, converted to an equivalent monthly rate, gives about 90,688 before fees. This is a calculation, not a prediction of an investment's performance.
Now simplify a 1% annual fee as a one-percentage-point reduction in the assumed annual rate. At 5%, the ending balance is about 81,161. That gap includes both the costs and the growth those deducted amounts no longer earn. Actual fees can be charged differently.

A future number has a future price tag
Inflation means a broad rise in prices reduces what a unit of money buys. If inflation were a constant 2% a year, that 81,161 would buy roughly what 54,619 buys today. Your own costs may rise differently from a published inflation average.
Do not subtract the nominal 48,000 of contributions from the inflation-adjusted 54,619 and call the difference your real profit. Those figures use different time bases.
Real life does not follow a smooth line
Market returns vary and losses are possible. The order of returns also matters when you add or withdraw money. A smooth curve helps explain an assumption; it cannot show every risk. Taxes and currency conversion can change your result too.
Use the illustration to compare possibilities. Then ask a more useful question than 'How rich will I be?': 'Is my contribution affordable, and what would I change if results were lower?'
ONE ACTION FOR TODAY
Stress-test the story
- Start with a contribution you could maintain without borrowing for essentials.
- Compare the illustration with a lower assumed return and higher inflation. Notice which numbers change.
- Write down the fees, tax treatment and access conditions you would need to check before using a real product.
MAKE THE IDEA STICK
What does the illustrated 81,161 ending balance tell you?
